According to one embodiment of the present disclosure, an optical package is provided comprising a laser source and a wavelength conversion device.

The input face of the wavelength conversion device comprises an α-cut facet and β-cut facet. The α-cut facet of the input face is oriented at a horizontal angle α, relative to the waveguide of the wavelength conversion device to permit proximity coupling of the output face of the laser source and the input face of the wavelength conversion device. The β-cut facet of the input face is oriented at a horizontal angle β, relative to the waveguide of the wavelength conversion device to cooperate with the horizontal tilt angle of the device to reduce back reflections from the input face of the wavelength conversion device into the laser source. Additional embodiments are disclosed.

    摘要： A method for aligning an opto-electronic component assembly (OECA) on a substrate includes positioning a substrate on an assembly surface and positioning an OECA on the substrate such that a first OECA alignment face projects from a first substrate alignment face. The substrate and the OECA are advanced towards a contact face of a first assembly alignment mechanism such that the first substrate alignment face contacts the contact face of the first assembly alignment mechanism after the first OECA alignment face contacts the contact face. The OECA is displaced relative to the first substrate alignment face when the first OECA alignment face contacts the contact face and the substrate continues to move towards the contact face thereby aligning the OECA on the substrate relative to the first substrate alignment face.

The method of making the stub lens element includes drawing a rod of optical material and processing the drawn rod to form a lens integrally connected to a stub section. The methods also include operably supporting an optical fiber and a stub lens element in a cooperative optical relationship to form a stub lens sub-assembly. The methods also include operably supporting the stub lens sub-assembly and a light-deflecting member in a cooperative optical relationship to form a probe optical assembly that has a folded optical path.
